Glucose metabolism begins with its transport into cells via GLUT transporters, where it is phosphorylated to glucose 6 phosphate (Glucose 6 P). This molecule can enter various pathways, including the pentose phosphate pathway or hexosamine biosynthesis. Do we need to memorize the structures of the pentose phosphate pathway molecules (e.g. pics 1 and 2) if we want a 130+? Also do we need to know the glutathione part HMP also known as the Pentose phosphate pathway. Consists of two irreversible oxidative rxs followed by a series of reversible Hexose Monophosphate Pathway or Pentose Phosphate Pathway Animations PharmaXChange.info Pentose Phosphate Pathway The Medical Biochemistry Page
